Abstract: Wireless technologies are the present and the future of network communications. However, the support of real-time data transmission in wireless communications --- providing support for execution of well-timed networked operations --- is still an open issue, not fully addressed by current wireless network standards and technologies. Thus, this paper proposes a solution to enhance the timeliness of wireless communications without a need for fundamental modifications to the standard specifications. The IEEE 802.15.4 wireless network is used as a relevant case study. Our main contributions in this paper are: (a) a proposal to enhance the timeliness of wireless communications; (b) the extension of the data frame transmission service in order to control the effects of temporary partitions caused by disturbances in the medium and medium access control protocols; (c) a strategy to reduce the negative effects caused by the aforementioned disturbances.
